Which spider is characterized by having an orange hourglass marking?

The spider that is characterized by having an orange hourglass marking is the Black Widow Spider. This distinctive marking is typically found on the underside of the female Black Widow's abdomen, and it can be a bright red or orange, which contributes to its identification. The Black Widow is known for its potent venom and its unique shape, which can appear glossy and black in color.

In contrast, the Brown Recluse Spider is recognized for its violin-shaped marking and is usually a brownish color, while the Tarantula is a large and hairy spider that does not have any noticeable hourglass marking. The Brown Widow Spider, while similar to the Black Widow, is typically lighter in color and may have a more muted hourglass marking, often in yellow or orange, but it does not have the same pronounced appearance as the Black Widow.
